Yeah, you're right. Actually I'm not sure yet if I'll paint/clear coat or even anodize them since I can have those professionally anodized for cheap, maybe even for free.JimVonBaden wrote: ↑Jan 15 2021 11:31pmNo matter what, make sure you at least clear coat them, or they will begin to corrode.

Re: Daly or other BMS for 14s 52V pack
I'm using the ANT BMS, they are in my opionion better than the Daly, mainly because they have a much higher balancing current (200mA vs 30mA) and because they can work with any number of cells (you can buy a 24S and it will still work if you only use 12S, you are not stuck with the amount of cells y...

Re: Electric Roadster Motorbike
Well it as the weekend, so I had some spare time, plus I spend most of my evenings in the garage during the week. :wink: I made some interesting progress those past two days. First, I finished the BMS enclosure. I'll just have to add the wires for the screen later, but aside from that it is finished...

Re: Electric Roadster Motorbike
Still working on the BMS: First I soldered the big copper bars. It wasn't as difficult as I thought it would be, I just heated the bars with a blowtorch, heated the BMS with my 100W soldering iron, used plenty of flux and well it worked just fine: IMG_20210108_233659.jpg Next I designed and printed ...

Re: Electric Roadster Motorbike
Although that controller is so large it will probably never overheat without burning out the motor first, why not rotate the controller so that the aluminium cooling plate is facing the front of the bike and thus the air flow when riding? You could weld tabs/strips to the front down tube to mount t...

Re: Electric Roadster Motorbike
Makes me question if QS sold me the correct size controller. I simply asked them to provide the matching Kelly controller and I didn't question it as I am still very new to this hobby. I think QS is right becaue they propose you a safe solution. Meaning thats there is little chance for you that any...

Nice build! About that 3d printer. You must be using a 1mm nozzle. What was your layer thickness on the cover? I’m envious as I’d love to print an entire bike wheel, need 600 x 600 min. Have you considered the wax filament for the sand casting that you want to do? Thanks Skaiwerd! On this printer I...

Re: Electric Roadster Motorbike
Really cool build and amazing rate of progress! I'm impressed If you're worried about the controller providing too much power for the motor, maybe you could try applying some "statorade" to the hub motor - https://ebikes.ca/product-info/grin-products/statorade.html - they claim "you ...

Re: Electric Roadster Motorbike
Hope you have a hefty torque arm for the motor You're kidding, right? There is a torque plate and the whole steel swing arm is a torque arm :wink: Actually that's a valid question: currently I'm only using the original QS torque plates, which, from my experience, aren't always up to the task when i...

Love this build. Well done! Can't wait to see the finished product. Thanks darkmunk, much appreciated! I can't wait to have it finished either, but it's coming along pretty well so far. Some progress over the past week: I worked on a stand for the bike. The original one was really too low so that w...

Re: Electric Roadster Motorbike
Really taking shape, jealous off your workshop too. My first thought on the NaOH on the fork was make it a thick slurry and paint it on with a brush and wipe off after 5-10 minutes. Ideally less mess and more control over where it touches. I'd get some elbow length gloves before doing it though, ac...

Re: Electric Roadster Motorbike
I wonder about the inside of the fork tubes, they will probably be treated with something too. Hopefully something more wear resistant. Do you plan to seal them somehow when you do the treatment? Ooohhh that's a really great remark, thanks a lot for bringing it out! I haven't thought about that at ...

Re: Electric Roadster Motorbike
Thanks Shazzy! I had some more 22mm carbon tubes, and since I'm confident this stuff is very solid now and since the handlebars were the same diameter, I decided to make handlebars out of it. It was easy to make, Just had to cut two bars of the same lenght, then gave both a bit of lathe work to get ...

Re: Small space, big power?

Re: Small space, big power?
Was a mountain goat as I could stop on a 20% grade and the thing would climb Mt. Everest, good luck doing that on a hub motor. We are talking about a kymco spade here, it's a street bike so that's a very different use case, requiring different specs :wink: Good luck doing both 20% climbs and 130+ k...

Re: Small space, big power?
I should be able to fit A123 20AH's, but the pack would be incredibly wide for the bike and still have less capacity than the cylindrical options. I assume that by "cylindrical options" you mean 18650 cells that output 3.7V, so not LiFePO4 chemistry. In which case, there's something to be...

What are the "many" drawbacks for mid-drive. The only two I can think of are space and having to maintain the chain. Main drawback is of course space, which leads to several subsequent drawbacks: Less battery space means either less capacity and/or less voltage Less voltage usually means ...

Re: Small space, big power?
Space is definitely going to be very limited, but I knew that when I chose such a tiny motorcycle to convert and then opted not to get a hub motor. My 3KWH target might be too ambitious, and I'm okay with something lower if that's what's necessary. I haven't paid attention to that point: why is it ...
